CellSight Privacy Policy
Effective: October 24, 2026
Danpung Electronics (“we”) operates the Android app CellSight (package dpe.cellsight) and is responsible for the processing described here.
1. Information the app processes
The app records battery status on your device to estimate the battery’s actual capacity (health).
- Recorded data: time, charge level, charging state and charger type, current, voltage, temperature and charge counter. The app also stores charging summaries made from these records (start and end level, estimated capacity, internal resistance, temperatures), and the rated capacity and alert settings you enter.
- This data stays on your device and is never sent to us. We run no servers that receive user data, and app data is excluded from Android backups.
- The app has no sign-up or login and does not collect your name, phone number or email.
- If you email us, we process your address and message to reply, and delete them one year after the request is resolved.
2. Advertising (Google AdMob)
The app shows one AdMob banner provided by Google LLC. Google’s SDK automatically collects:
| Data | Purpose |
|---|---|
| Advertising ID and other device identifiers | Ad delivery and measurement, personalized ads, fraud prevention |
| IP address (may indicate approximate location) | Ad delivery, fraud prevention |
| Ad impressions, clicks and other in-app interactions | Ad measurement, personalized ads |
| Device model, OS version, crash and performance data | Ad delivery, diagnostics |
- See the Google Privacy Policy and How Google uses information from sites or apps that use our services.
- Recipient: Google LLC, as an independent controller for this data.
- Users in the EEA, UK and Switzerland are asked for consent through Google’s consent tool on first launch; ads are requested only within that consent (legal basis: consent, and legitimate interest where Google relies on it). Change it any time under About (at the bottom of the app) › “Privacy settings (ad consent)”.
3. International transfers
Ad data is transferred to Google LLC and processed in the United States and other countries where Google operates, under Google’s safeguards described in its privacy policy.
4. Advertising ID and your choices
The app uses no cookies, but uses the Android advertising ID for ads. You can delete or reset it in Android settings › Privacy (or Google) › Ads; once deleted it is not used for personalized ads.
5. Retention
We store no app user data. On your device, battery records are deleted automatically after 14 days and charging summaries are kept until you delete them (About › “Delete all records”). Everything is removed when you uninstall the app. Email inquiries are deleted as described in section 1.
6. Sharing and processors
We do not share your personal data with third parties or use processors, apart from the data collected by Google’s ad SDK described above.
7. Permissions
Notifications (requested on Android 13 and later): the ongoing recording notification and the charge-level alert you set; the rest of the app works if you decline. Foreground service (special use): keeps recording so charging sessions are not missed while the app is closed. Boot completed: restarts recording after a reboot or app update. Internet and advertising ID: ads. All except notifications are granted at install time.
8. Children
The app is not directed to children under 13 (under 14 in Korea) and does not knowingly collect their data.
9. Your rights
You may request access, correction, deletion or restriction of processing, and withdraw consent, by writing to dpe@dpeapps.xyz. As we hold no app user data, ad-related data can be managed with Google directly or limited as described above. You may also object to processing. EEA/UK users may lodge a complaint with their data protection authority.
10. Security
The app is designed not to send battery records anywhere and excludes them from Android backups; the ad SDK’s traffic is encrypted with TLS.
